Sounds like jealousy to me.
I liked having one, especially after a long day at work, but the maintenance takes a bit of keeping up with and they use a lot of leccy.
Not if you do it right!
I run mine off a heat exchanger via the central heating system.
Since it is very well insulated, it doesn't lose much heat, and what it does, heats the bathroom.
It works, in effect, like a mass oven.
Since I heat my house entirely with wood, of which i have an abundance, all it costs to run the hottub, is the
"leccy" that runs the pump to the filter/heat exchanger unit.
I have a massive filter for a much larger swimming pool, so that is good for a year without changing.
So, basically, all the maintenance is keeping PH right and tossing some clorine in every second week.
I've wanted a hottub ever since I came across them in California in 80-82 ( There is a great place in
Arcata, where I used to live, where you can rent them by the hour. They are out door, in separate huts. My Cali girl friend and I used to go down there, rent one for an evening, smoke weed, drink sake and make waves. Those were the days
)
I had a long time to think this through and come up with a good working solution, and it really does run well.
Having got a nice Swiss lady to enjoy it with after going horse riding in the Danish winter weather is a plus, too.
